ECO4 Scheme Solar Panels Wales – Can You Get Free Solar Panels?
The ECO4 scheme is a UK government-backed grant programme that funds energy efficiency improvements for low-income and vulnerable households. If you live in Wales and meet the eligibility criteria, you could get solar panels installed for free. The scheme closes to new applicants on 31 December 2026.
What Is the ECO4 Scheme?
The Energy Company Obligation 4 (ECO4) is a government initiative that requires large energy suppliers with more than 150,000 customers to fund energy efficiency upgrades in eligible homes. Suppliers including British Gas, EDF, E.ON, Scottish Power and SSE are obligated to deliver these measures.
ECO4 has been running since April 2022 and has funded more than 660,000 energy efficiency measures across the UK, including over 38,000 solar panel installations. The scheme targets homes with low Energy Performance Certificate (EPC) ratings – typically bands D through G – and focuses on households most likely to experience fuel poverty.
Can You Get Solar Panels Through ECO4 in Wales?
Yes. Solar PV is a recognised measure under ECO4 and grants are being issued to qualifying households in Wales right now.
Properties with electric storage heaters, panel heaters or air source heat pumps are among the most likely to qualify for solar panels under the scheme. If your home uses an electric heating system rather than gas central heating, your chances of receiving solar PV funding increase.
Who Qualifies for ECO4 in Wales?
There are two main routes to eligibility.
Benefits Route
If a member of your household receives any of the following means-tested benefits, you may qualify:
- Universal Credit
- Pension Credit
- Housing Benefit
- Child Benefit (with annual income below specific thresholds)
- Child Tax Credits
- Income Support
- Income-based Jobseeker’s Allowance
- Income-related Employment and Support Allowance
LA Flex Route
Even if you do not receive benefits, you could still qualify through Local Authority Flexible Eligibility (LA Flex). This allows councils in Wales to recommend households for ECO4 funding based on:
- Household income below £31,000
- Medical vulnerability or health conditions worsened by living in a cold home
- Fuel debt or disconnection from a prepayment meter
- Other indicators of fuel poverty
How to Apply for ECO4 Solar Panels in Wales
You cannot apply directly through your local council. The process works through approved installers and agents:
- Contact an ECO4-approved installer or agent operating in Wales
- They check your initial eligibility based on your benefits and property details
- If you pass the initial check, a free property survey is arranged
- The installer obtains or reviews your EPC rating
- If approved, the installation is scheduled and fully funded through the scheme
The contract for any work is between you and the installer, not the local council. There is no cost to you if you fully qualify.
How Much Could You Save With Solar Panels?
A typical solar PV installation in Wales generates around 3,000 kWh of electricity per year. The average Welsh household uses approximately 2,900 kWh annually, so a well-sized system can cover most of your electricity needs.
You can also earn money through the Smart Export Guarantee (SEG), which pays you for surplus electricity you export back to the grid.
Other Solar Panel Grants in Wales
ECO4 is the main route for funded solar panels in Wales, but other support exists.
Warm Homes Nest Scheme – This Welsh Government programme has been running since 2011 and has spent over £251 million helping more than 66,000 households with free energy efficiency improvements including solar panels, insulation and heating systems.
Green Homes Wales – Another Welsh Government initiative offering support for energy efficiency upgrades.
Warm Homes Plan – The UK Government announced this £15 billion programme in January 2026 targeting five million homes by 2030. Eligibility details are still being confirmed.
For most households, ECO4 remains the most accessible and established route to funded residential solar panel installation.
Is It Worth Getting Solar Panels in Wales?
Wales receives generous daylight hours throughout the year. Solar PV works on daylight rather than direct heat, so the Welsh climate is suitable for generating solar energy. Most roofs in Wales have a pitch between 30 and 50 degrees, which works well for solar panels. South-facing roofs are ideal, though south-east and south-west orientations also perform well.
If you qualify for ECO4 funding, the installation costs nothing and the savings start immediately. Even without a grant, solar panels remain a strong investment. A typical system pays for itself within 6 to 8 years and continues generating free electricity for 25 years or more.
What Happens When ECO4 Ends?
The scheme closes to new applicants on 31 December 2026. After that, households in Wales will need alternative routes for solar funding. The Warm Homes Plan may offer a replacement, but details remain limited. If you think you might qualify, apply sooner rather than later. Demand increases as the deadline approaches.
